RETAINING ATTACHMENT sort OPERATING- TABLES.

Application fi ea'a rii 19, 1921.. Serial in). 462,731.

To all whom it may concern.

Be it known that l, Lno L. LUX, a citizen of the United States, residing at the city of Greeley, and county of "Weld and State of Colorado, have invented certain new and useful Improvements in Retaining Attaclr ments for Operating Tables; and I do doclare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

The object of this invention is to provide a simple device which may be quickly attached to operating tables to assist in holding the patient.

riefly, the invention comprises a clamp adapted to be secured to the table and having a positively operating strap retainer for holding one end of the strap. Two forms of the clamp are used. One form has one end of the strap permanently secured thereto on the inner face of one of the jaws where it may serve as a cushion for the clamp, said clamp also carrying on its outer face a swinging retainer to engage the other end of the strap. The other form of the clamp is to be used in connection with the first form where it is impossible to engage the free end of the strap with said first clamp. In this second form, the clamp has a swinging retainer disposed in an opposite direction from the retainer of the other form.

In the drawings:

Fig. 1 is an elevation showing one form of clamp as indicated by the line 1--] of Fig. 2;

Fig. 2 is a face view thereof taken from the line 22 of Fig. 1;

Fig. 3 is a vertical section through the other form of clamp;

Fig. 4 is a view showing one use of the device where both forms of clamp are required;

Fig. 5 is a view showing the use where only one clamp is employed;

Fig. 6 is a face view of the form of clamp of Fig. 3; and

Fig. 7 is a detail taken from the line 7 of Fig. at.

The clamp comprises a body member 10 having a aw 12 which receives the screw 1&-

carrying on its innerend an engaging head 15 swiveled on the screw 1 by means of gers 16 which enter a groove 18 in the screw, the outer end of the screw being provided with a thumb piece 20. The body 10 carries a second jaw 22 parallel with the jaw 12, said jaw 22 having a pair of offset ears 25 carrying between them a bar 26. Directly above said ears 25 is another pair of cars 28 on said jaw 22 which carry a transverse rod or bar 30. In the form of Figs. 1 and 2 a strap retaining plate 32 is pivoted upon the bar 26 by means of an eye 34, the free end of the plate being toothed, as shown. to. insure firm engagement with the strap 8. The inner face of the jaw 22 is provided. with a cushioning pad 35 to engage directly with the table T to avoid marring the outer surface thereof. The clamping head 15 and screw 14: are positioned under the table and on the inner side of that portion to which the clamp is secured.

In the form of clamp shown in Figs. 3. 5 and 6, the strap retainingjaw 36 is pivoted to the upper bar 30 by means of an eye 38, its lower end being toothed, as shown to positively engage the strap S, the plate 36 co-operating with the bar 26 in the same manner which the plate 32 co-operates with the bar 80. With this second form of clamp the strap S is permanently secured, as by means of a rivet L0, to the inner face of the jaw 22 so that the fixed end of said strap serves as a cushion in place of the pad 35 ()f Fig. 1. With this form the strap S may he passed upward and over the table and thence under the table and over the rod 26 against which it is secured by the plate 36.

However, where it is not possible to pass the strap around the table in this manner, the other form of clamp must also be em ployed. Such use is illustrated in Figs. -& and 7. Here the second form of clamp is secured to the table as before, the strap be ing passed around the patient as indicated in Fig. et and then returned to the side of the table at a spaced point. At this point the first form of clamp, as shown in Figs. 1 and 2 is used, the strap being brought downward behind the bar 30 and secured thereagainst by the plate 32.

I claim:

1. A retainer comprising a pair of opposed jaws, means on one jaw to clamp the device on a table, and means on the outer bar to engage and hold a strap against the other bar.

4:. In combination, a clamp adapted to be secured to a table, strap ser'ured to said. clamp, a second clamp adapted to be secured to the table, a pair of bars mounted on. said second clamp, and a plate mounted on one bar to engage and hold the strap against the other bar.

In testimony whereof I allix mv signature.
